Line attenuation help?


[link to this post]
 
Hi, I am hoping an expert on here can help me make sense of my broadband challenge. We are 1 mile from the cabinet and have just upgraded to FTTC. We were previously getting 5.5mb download and 0.9mb upload on ADSL2+. Now on fibre we get 13mb download (which is much higher than I expected) and a 0.35mb upload. The upload speed is what we were hoping to improve and it makes no sense to me that the download would more than double, while the upload more than halved after moving to fibre. When I dug further into the stats I get more confused. The line attenuation for download is 29db, but for upload it's 79db. I thought that download attenuation would always naturally be a higher number than upload given the greater frequency applied to download on the line?? So I cannot fathom what is happening here? Please help!

Sounds like a problem. What modem are you using?

Current rate (Kbps): 487(upstream), 17806(downstream)
Max rate (Kbps): 488(upstream), 17448(downstream)
SNR margin: 7.5(upstream), 5.4(downstream)
Line attenuation: 72.7(upstream), 29.1(downstream)

These are all the stats my router will provide. I have a TP-link router.

Thanks for helping!!

This is brand new as I wanted to try an alternative to the technicolor router from SSE.

Thanks for helping!

Summat not right there, have you anything else to test with, and maybe a description of the set up in the property ?

What are your WAN settings please? Including the ADSL/2/2+/VDSL2/All settings.

As others and you have said, those stats are crazy. The upstream suggests an ADSLx setup.

here are all the settings I can find on the router - not 100% sure what you need:

Internet Settings
Name: pppoe_ptm_101_2_d
MAC Address: 5A:C7:BF:01:A1:74
Subnet Mask: 255.255.255.255
Default Gateway: 62.72.136.44
Primary DNS: 89.145.254.78
Secondary DNS: 94.30.127.100
Connection Type: PPPoE

LAN settings
MAC Address: 50:C7:BF:01:A1:73
IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
DHCP: On

DSL settings (excluding ones already posted)
Line Status: Connected
DSL Modulation Type: VDSL2
Annex Type: Annex A/L

Other settings
WAN interface name: pppoe_ptm_101_2_d
VPI/VCI or VID: 101
DSL Modulation Type: Auto Sync-up
Bit Swap: Enabled
SRA: Disabled

All the additional parental controls and security controls are disabled.

Please let me know if I need to source any other data? This appears to be all my router has apart from he wifi settings, but i am hard wired currently.

Also FYI. Using the advanced settings on the btwholesale speed checker, here are the IP profile stats for the line:

Download
Download speedachieved during the test was - 13.51 Mbps
For your connection, the acceptable range of speedsis 10.88 Mbps-15.55 Mbps .
IP Profile for your line is - 15.55 Mbps

Upload
Upload speed achieved during the test was - 0.38Mbps
Upstream Rate IP profile on your line is - 10 Mbps

The bit that surprises me is the IP profile on the upload side?

The upload speed should be over 1mb (it used to be around this on ADSL), but it cannot get about .38 and is usually .35.

Looks like you are indeed on VDSL {FTTC}.

The upload IP Profile merely denotes what package you're on. 10 = 40/10 or 55/10.
